Maybe vertical Us tied to with one or two horizontal runs down the trench? 1' on center where roll up door is. Otherwise 2 possibly 3' on center? I don't think epoxy would be required for the 1/2" where it pins into the existing slab. Thoughts? Thank you

So today my concrete contractor bailed on a project. I was relying on him to do the rebar after he told me he'd done lots of grate trenches. He also said he was going to pour it in one shot. Seemed like the hard way to do it but I'm not the concrete guy. So now I'm in a lurch. I found someone...

We are preparing to do a trench drain project. The frames are made of 2” steel angle with headed concrete anchors. My question is should I do some type of rust inhibiting prep to the outside of the angle where it will be in contact with the concrete? If I primed the surface, with the...

I am a big believer in trust but verify. Now I have two sources that agree while I wait on the pump supplier to get back to me, and now I am ready when they do. I can also cross it off my list and move on to the next thing.

Thanks for the confirmation and spell check. For whatever reason my brain hates that H.

Based on what I've found for two separate pumps and chemicals. EPDM is the preferred seal material for a stainless pump moving sodium hydroxide with PH between 10-12 Viton is the preferred seal material for a stainless pump moving hypochlorous acid with PH between 6-7 Can anyone confirm this...

Ha. Made perfect sense as I was thinking and writing about it. Definitely more rambling rereading it. Let's start with a few picture. Pump data plate Basic drawing of plumbing Now for the background. This is a used cart wash (Think mini car wash.) It's one of those someone decided to buy...

When you say condenser are you actually referring to the chiller's water-cooled condenser? I.E. You are pumping to a cooling tower. Otherwise you would be talking about what I would call cooled process water. I.E. going to radiators with blowers to cool a room. I'm sure there is fancy sounding...

Thank you it looks like it will be a handy reference.

The pumps in the machine won't cut it. I'm considering feeding the spray pump with another pump. The alternative is mounting something a 25 gallon tank above the machine and topping it off as it's used. Would I be correct in thinking along these lines. The spray pump in it's original...

They run all three pumps on each chiller at the same time? 9 pumps are currently running all the time? Your current design will end up running 5? Seems like each triplex skid would have a spare pump on it after the upgrade. We run triplex pump skids for just that reason. Close valves to pump...

I did say check the specs.... Here's one that's closer. 100PSI @ 80 GPM with lift of 63". Doesn't list solids spec though. https://pumpbiz.com/lp-fire-pumps-portable-two-stage-7ak306-lp Curve http://www.darley.com/wp-content/uploads/2022/09/AK306-C577.pdf

Finding a single phase trash pump with that kind of output is going to be challenging if not impossible. You could do it with a phase inverter. You are probably looking at a 45 amp circuit. You will still need to solve venting / priming. Depending on how committed you are to having on demand...

Yeah I'm going to have to move them. The pumps aren't going to pull that much. Should I need to do the math again in the future are TDSH and Equivalent length always interchangeable?

I had the same thought when I woke up this morning. There are a few things I'll have to sort to go this way.

I have an application where the supply tank needs to be mounted on the other side of the room from a machine with pumps in it. I'm having trouble finding information on calculating the TDSH for this pipe configuration. Material either 1" or 1.5" CPVC I believe these are the correct...

In that case lick your middle and pointer finger. Put one on the big brown wire lug and the other on the big orange wire lug. Always want to check that the power is off first. Then you will most likely need a wire stretcher. You'll have to ask around but I'm sure you can find an electrician...

Did I say 36"? I meant 35" Thank you

SlideRuleEra no need to go away. 1) I'd say both but they lean towards as economical as possible. They do tend to question how necessary every piece is, but with a solid explanation or a hard no they come around. As to the other questions I try to do everything as the various codes would...
